Main process crash. I clicked to open the panel of [enhanced-h264ify](https://addons.mozilla.org/en-US/firefox/addon/enhanced-h264ify/). It doesn't seem to be reproducible. gfx.webrender.max-partial-present-rects is 0 (default), but I have manually set gfx.webrender.panic-on-gl-error to true. This bug is for crash report bp-9d065196-d957-4144-9e88-9ee940200614.
